The short answer
Straightening a buckled alloy in the UK typically costs around £50–£120 per wheel, while welding a cracked alloy usually costs £60–£150+, depending on the crack's size and location. These are structural repairs, not cosmetic ones, and they are only done where a specialist judges the wheel safe to repair. Some damage cannot be safely fixed — cracks across stressed areas, severe buckles, or hairline cracks on the inner barrel — and the wheel must be replaced instead. A refinish (paint, powder-coat or diamond-cut) is usually a separate cost on top if you also want the wheel to look new. Always have buckle or crack damage assessed before driving, as a failing wheel is a safety risk.
A buckled or cracked alloy is more serious than a kerb scuff because it affects how the wheel performs at speed and holds air. The sections below give indicative UK costs, explain what can and cannot be repaired safely, and cover when replacement is the right call.

Buckle and crack repair costs
Buckle straightening uses a hydraulic press or roller to work the bent rim back towards true; crack welding adds material to seal a crack in aluminium, which then needs re-machining and refinishing. Both are skilled, equipment-led jobs, so the cost reflects the work and the assessment, not just materials. The ranges below are indicative and depend heavily on severity, location and whether a refinish is added. Figures vary by region.
| Repair | Indicative cost | Notes |
|---|---|---|
| Minor buckle straighten | £50–£90 | Small bend, repairable |
| Severe buckle straighten | £90–£120+ | More work, may not fully true |
| Crack weld (safe area) | £60–£150+ | Weld, re-machine, refinish |
| Refinish after structural repair | Extra | Paint/powder/diamond-cut |
| Replacement (not repairable) | Wheel cost varies | OEM vs aftermarket |

What can and cannot be repaired
Whether a damaged alloy can be saved depends on where and how badly it is damaged. A buckle — where the rim has been pushed out of true by a pothole or kerb impact — can often be straightened if the bend is moderate and the metal has not cracked. After straightening, the wheel is checked for trueness and for air-tightness, and rebalanced. A buckle that is too severe, or one that has stretched and weakened the metal, may not return to a safe, round shape and is then a replacement.
A crack can sometimes be welded, but only in the right place. A crack on the face or a non-stressed part of the rim may be safely welded, re-machined and refinished. A crack that runs across a stressed area, a spoke, or the inner barrel where the wheel takes load and holds the tyre bead is far riskier, and many specialists will not weld it because a repaired wheel that later fails at speed is dangerous. The honest answer from a good shop is sometimes 'this one needs replacing', and that judgement is part of what you are paying for.
Repair cost vs replacing the wheel
The decision between repairing and replacing comes down to safety first, then cost. If a buckle or crack can be repaired safely, doing so is usually cheaper than a new wheel — especially for premium or OEM alloys, where a genuine replacement can be expensive and aftermarket matches are not always available. A successful straighten or weld plus a refinish can restore the wheel for less than buying new.
Where the damage is unsafe to repair, replacement is the only responsible route, and the cost then depends on whether you fit a genuine OEM wheel (dearest, exact match), a used OEM wheel (cheaper, condition varies) or an aftermarket equivalent (varies widely). It is also worth remembering that a wheel damaged badly enough to crack may have stressed its neighbours or the tyre, so a check of the surrounding wheels and tyres is sensible after a heavy pothole hit. Whatever the route, the structural assessment should come first: a wheel that holds air and looks fine can still be unsafe if the metal has been weakened, which is why a specialist inspection — not just a visual glance — is the starting point for pricing this kind of damage.
Frequently asked questions
Is it safe to drive on a buckled alloy?
Not for long. A buckled wheel can cause vibration, uneven tyre wear, slow air loss and poor handling, and a badly buckled or cracked wheel can fail. Have it assessed by a specialist before continuing to drive, and treat any vibration after a pothole impact as a reason to get it checked.
Can a cracked alloy wheel be welded?
Sometimes, depending on where the crack is. A crack on the face or a non-stressed area may be safely welded, re-machined and refinished. Cracks across stressed areas, spokes or the inner barrel are often unsafe to repair, and the wheel must be replaced instead. A specialist should make that call.
Is it cheaper to repair or replace a buckled alloy?
If it can be repaired safely, straightening is usually cheaper than a new wheel, especially for premium or OEM alloys. If the damage is unsafe to repair, replacement is the only option, and the cost then depends on whether you fit a genuine, used or aftermarket wheel.
